UIST – Imaging: Template Sequences

UIST – Imaging: Template Sequences

UIST observing programmes are set up under the UIST ORAC-OMP ORACOT . Your starting point will be the template sequences in the UIST library which contains the sequences described below.

UIST Non-Thermal Imaging Template MSBs

MSBContentsDescriptionDR Recipes Used
5 Point JitterTarget component
UIST component
DR component
Observe sequence
Observations consist of a dark followed by one exposure at each of 5 telescope positions. Useful for brighter point sources. BRIGHT_POINT_SOURCE
JITTER_SELF_FLAT
9 Point JitterTarget component
UIST component
DR component
Observe sequence
Observations consist of a dark followed by one exposure at each of 9 telescope positions. Useful for fainter point sources. JITTER_SELF_FLAT
N-colour JitterTarget component
UIST component
DR component
Observe sequence
Observations consist of a dark followed by a jitter set through multiple filters using the imaging iteratorJITTER_SELF_FLAT_NCOLOUR
Quadrant JitterTarget component
UIST component
DR component
Observe sequence
Observations consist of a dark followed by one exposure at 4 telescope positions, one in each quadrant. Useful for extended sources of size less than one quad, or 60″ for the 0.12 camera.QUADRANT_JITTER
Extended 3×3 Target component
UIST component
DR component
Observe sequence
Observations consist of a dark followed by one exposure at 19 telescope positions, starting and ending at a sky offset. Useful for mapping extended sources smaller than about 2 arc minutes. EXTENDED_3x3
Extended 5×5Target component
UIST component
DR component
Observe sequence
Observations consist of a dark followed by one exposure at 51 telescope positions, starting and ending at a sky offset. Useful for mapping extended sources smaller than about 3 arc minutes. EXPENDED_5x5

UIST Thermal Imaging Template MSBs

L’ 0.12″/pix Nod4Target component
UIST component
DR component
Observe sequence
Observations consist of a dark followed by one exposure at each of 4 telescope positions. Useful for brighter point sources. Note exposure set by camera and filter and should not be changed. NOD_SELF_FLAT_NO_MASK
L’ 0.12″/pix Nod8Target component
UIST component
DR component
Observe sequence
Observations consist of a dark followed by one exposure at each of 8 telescope positions, diagonally placed on the array to avoid the lower-QE lower right quadrant. Useful for fainter point sources. Note exposure set by camera and filter and should changed.NOD_SELF_FLAT_NO_MASK
L’ 0.06″/pix Nod8Target component
UIST component
DR component
Observe sequence
Same as above but with exposure and offsets scaled for the smaller pixels camera.NOD_SELF_FLAT_NO_MASK
M’ 0.12″/pix Nod8Target component
